I see that, but the thing is there's been almost no notice, which means not only work commitments, but other commitments are going to be hard to rearrange. Children are in school, for example - obviously not everyone has children (I don't) but according to statistics, more do than don't - so even people who work part time would still have to make after school arrangements (because this isn't just a couple of hours, it's an all day queue). And if you don't live in London, you have travel time and the expense of travel to add to the difficulty.
